Crytek has announced some of its websites have been breached, so it has taken four offline. The publisher has now confirmed that user accounts may have become compromised.

UPDATE: Crytek has now issued a statement to Eurogamer to make clear that user details may have been accessed as part of the security breach and to urge membes to change their credentials as soon as possible.

“Our Crytek.com, Mycryengine.com, Crydev.net and MyCrysis.com sites were all subject to a security breach that may have resulted in some users’ login data being compromised. Although it is uncertain whether the incident led to the copying and decryption of email addresses and passwords, it is possible that users with accounts at these websites have had personal data copied.

“On Friday afternoon we started to contact all affected users via email and informed them of the potential security breach. Next time account holders visit crydev.net, mycryengine.com or mycrysis.com, they will be asked to change their passwords during log in.

“We would like to reiterate our suggestion to account holders that they change their password for other locations online if it is the same as their login data for the affected Crytek sites.

“Final details of when our sites will be back online will be communicated as soon as possible. We’re currently doing everything in our power to ensure our sites and, more importantly, our users, are not affected by such issues in future.

“Once again, we would like to offer our sincere apologies to everyone affected by this incident, and thank our users for the level of understanding they have shown.”

ORIGINAL STORY: Users will be asked to changed their passwords once Crytek.com, Mycryengine.com, Crydev.net, and MyCrysis.com are back online. The firm said it became aware of “suspicious activity” so it “acted quickly to take those websites offline for security reasons.” Crytek says if you use the same passwords elsewhere on another site, you should change them. It also said it is “working on getting all websites fully operational again as soon as possible.” Thanks Blue.
